8. At t = 8 seconds, the bicycle in Model 1 is 14 feet from the starting platform. a. Add a point to the position graph in Question 4 at t = 8 seconds. b. Based on this information, what is the value of... i. [ v(t) dt = [ v(t) at = The value of this integral (ii.) relates to both parts of Question 7. Explain. 9. For the bicycle in Model 1... a. Write down a definite integral that describes: i. The change in position ii. The change in position between t = 8 and t=10s. between t=0 and t = 10s. b. Use the grid in Model 1 to estimate the value of each these two definite integrals. c. Add a point to the graph in Question 4 at t = 10
